Hexagonal 304 stainless steel reducing bushing with male and female threaded ends

Value Brand

Value Brand 304 Stainless Steel Hex Reducing Bushing 1-1/2 x 1-1/4

SKU CH-9DA0-72A4Y

Connects 1-1/2 in male NPT to 1-1/4 in female NPT with a 304 stainless steel hex body for wrench tightening and corrosion resistance

  • 304 stainless steel resists corrosion and high temperatures
  • Hexagonal outer profile allows secure wrench tightening
  • MNPT to FNPT connection joins different pipe sizes
  • 1-1/2 in male and 1-1/4 in female nominal sizes
  • New condition ensures clean, undamaged threads for reliable sealing

What this fitting is and who uses it

This 304 stainless steel hex reducing bushing connects a 1-1/2 inch male NPT thread to a 1-1/4 inch female NPT thread. It is designed for plumbing and industrial piping systems where a secure, leak-resistant transition between different pipe sizes is required. The hexagonal profile allows tightening with a standard wrench. Suitable for installers and maintenance technicians working with compatible threaded components.

The specification that decides fit

The connection type is MNPT on one side and FNPT on the other with nominal pipe sizes of 1-1/2 inches male and 1-1/4 inches female. Both threads must match the existing piping exactly for a proper seal. The 304 stainless steel construction provides corrosion and temperature resistance within the manufacturer's rated pressure and temperature ranges. Verify thread standards and pressure ratings against your system requirements before installation.

Who this suits and who should look elsewhere

This bushing suits professionals reducing pipe size in stainless steel piping networks carrying fluids compatible with 304 grade material. It is not for systems requiring a different thread standard, a larger or smaller size step, or a material grade with higher corrosion resistance than 304 stainless provides. Buyers needing a different connection type or pressure class should select an alternative fitting.

Questions about this item

What does the 1-1/2 inch male NPT size mean when I thread it into my piping system?

The 1-1/2 inch male NPT end screws into a matching female threaded opening of the same nominal size, creating a tapered seal that tightens as you turn it with a wrench on the hex flats.

How do the MNPT and FNPT threads limit the pressure this bushing can handle?

NPT threads rely on taper engagement and sealant for a leak-resistant joint; the practical pressure limit depends on the 304 stainless steel rating and proper assembly rather than the thread standard alone.

What clearance do I need around the hex to tighten this reducing bushing?

The hexagonal outer profile is sized for a standard wrench or adjustable spanner; allow enough swing radius for the tool to engage the flats fully without obstruction from adjacent pipes or walls.
